Frequently asked questions

Answers about using Unitivo, supported units, shareable links, privacy, and advertising.

• Is Unitivo free?

  Yes. The converter is free to use. We may show ads through Google AdSense only if you consent to advertising cookies, as described in our Privacy policy.

• Do you store my conversions?

  Conversion values are processed in your browser. We do not require an account. Favorites and preferences (language, theme, cookie choices) are stored locally on your device unless you clear browser data.

• How accurate are the results?

  We apply standard international conversion factors. Temperature uses official formulas between Celsius, Fahrenheit, and Kelvin. For critical applications, cross-check with authoritative sources.

• Which units are supported?

  Eight categories: length, distance, mass, temperature, volume, speed, area, and time. Each category lists the units available in the dropdown menus and in the table view.

• How do shareable links work?

  When you convert, the URL can include the units and value (for example from, to, and v parameters). Copy the link with the Share button and open it later or send it to someone else to restore the same conversion.

• Why does the site use cookies?

  Essential cookies store your language and theme. With your consent, Google Analytics helps us understand traffic, and Google AdSense may show ads. You can accept, reject, or customize choices in the cookie banner or footer.

• Where is the privacy policy?

  Read the full Privacy policy linked in the footer (/en/privacy or /pt/privacy). It explains data processing, your rights, and how to change cookie settings.
